boys. back in 2011, camerada survived hurricane irene. so he paid close attention to reports of another potential hurricane headed his way in late october. >> it's been a very fickle storm, but it's going to be sucked in here, into the northeast somewhere. >> we were all hoping that the storm was going to blow more towards the south and not come north. >> a few miles away, at columbia university, climate scientist adam sobel was keeping an eye on sandy as well. >> at the beginning, look at that, that would be a big deal if that happened. but a week ahead of time, we don't take it that seriously. >> it is still four days away. this could have a bigger impact on new york city, connecticut, long island, new jersey, than irene did last year. >> as sandy moved north, it merged with a winter storm, creating a superstorm, double the size of a normal hurricane.
